Retroviral Attack on the Immune System

“The HIV/AIDS pandemic has evolved into the greatest global public health crisis, one that has progressed virtually unchecked in many of the poorest regions of the world for over two decades.” – IOM 2004

Human immunodeficiency virus (HIV) grows and evolves rapidly. HIV permanently inserts its genome into the genome of the infected cell and from there continues to make new viruses. Left untreated, the virus destroys important immune system cells. The resulting condition, AIDS for “acquired immunodeficiency syndrome,” increases the chance that the infected person will get life-threatening infections even with opportunistic organisms that would not normally cause disease.

There is still no cure for HIV, but infection can be prevented and the progression to AIDS can be controlled in many patients using antiretroviral drugs.
